I have a DB that belonged to my Grandfather. I'm not sure of the exact model because it is missing the tag and had no engine. It is a 2 piece frame with the clicker hubs on it. No bells or whistles.

Although it does have some sentimental value since it belonged to my Grandfather, I don't own any tools that do not get used. So I'm currently getting it into good mechanical condition to cultivate the garden.

I purchased a mostly complete speed changer for it. I say mostly because it was missing the Pivot Bracket and Pin (Part Number 575PA676). It is the bracket the bell crank attaches to. This should be pretty easy for me to fabricate, if I had dimensions for the location of the holes and pivot pin.

Please see my feeble attempt at a drawing of the plate. I need the length of "A" "B" & "C" (Actually just B&C since I already know the centers of the bolts). The filled circle would be the pin location with the open circles being the mounting holes.

Welcome to the forum! There are some David Bradley professionals here who will probably know the answer. I have one right now that is in line for some love and attention, but I don't claim to know much about them!!

(which is fantastic by the way), the bell crank stud is made as part of the transmission housing in the later DB's. I may be wrong as I only have the manuals for reference and have never seen one in person. Even if this is the case, the location of the 5/8" pivot pin should be in the same location as the models with the plate. If you could give the measurements from the pin center to the transmission cover bolt centers in the 1 & 2 o'clock position, this should be what I need.
